Thus, the apic device is not strictly an SMP option, 43# but it is a prerequisite for SMP. 44# 45# Notes: 46# 47# HTT CPUs should only be used if they are enabled in the BIOS. For 48# the ACPI case, ACPI only correctly tells us about any HTT CPUs if 49# they are enabled. However, most HTT systems do not list HTT CPUs 50# in the MP Table if they are enabled, thus we guess at the HTT CPUs 51# for the MP Table case. However, we shouldn't try to guess and use 52# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled 53# for the MP Table if the user explicitly asks for it via the 54# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT 55# disabled in your BIOS. 56# 57# IPI_PREEMPTION instructs the kernel to preempt threads running on other 58# CPUS if needed.

The default is double-clock mode on 99# BlueLightning CPU box. 100# 101# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 102# BlueLightning CPU. It works only with Cyrix FPU, and this option 103# should not be used with Intel FPU. 104# 105# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 106# 107# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 108# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 109# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 110# 111# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 112# mapped mode. Default is 2-way set associative mode. 113# 114# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables 115# reorder). This option should not be used if you use memory mapped 116# I/O device(s). 117# 118# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 119# machines. VmWare 3.x seems to emulate this instruction poorly, causing 120# the guest OS to run very slowly. This problem appears to be fixed in 121# VmWare 4.x, at least in version 4.5.2, so that enabling this option with 122# VmWare 4.x will result in locking operations to be 20-30 times slower. 123# Enabling this with an SMP kernel will cause the kernel to be unusable. 124# 125# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. 126# 127# CPU_ELAN enables support for AMDs ElanSC520 CPU. 128# CPU_ELAN_PPS enables precision timestamp code. 129# CPU_ELAN_XTAL sets the clock crystal frequency in Hz. 130# 131# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun 132# technology which allows to restrict power consumption of the CPU by 133# using group of hw.crusoe.* sysctls. 134# 135# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 136# 137# CPU_GEODE is for the SC1100 Geode embedded processor. This option 138# is necessary because the i8254 timecounter is toast. 139# 140# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 141# for i386 machines. 142# 143# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 144# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 145# (no clock delay). 146# 147# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used 148# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. 149# The default value is 5. 150# 151# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 152# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 153# 1). 154# 155# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option 156# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 157# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 158# 159# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 160# 161# CPU_SOEKRIS enables support www.soekris.com hardware. 162# 163# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 164# enters suspend mode following execution of HALT instruction. 165# 166# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). 167# 168# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 169# K5/K6/K6-2 CPUs. 170# 171# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 172# flush at hold state. 173# 174# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 175# without cache flush at hold state, and (2) write-back CPU cache on 176# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 177# 178# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 179# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 180# executed. This option is only needed if I586_CPU is also defined, 181# and should be included for any non-Pentium CPU that defines it. 182# 183# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 184# which indicates that the 15-16MB range is *definitely* not being 185# occupied by an ISA memory hole. 186# 187# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 188# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 189# These options may crash your system. 190# 191# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 192# in write-through mode when revision < 2.7. If revision of Cyrix 193# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 194# 195# NOTE 3: This option may cause failures for software that requires 196# locked cycles in order to operate correctly. 197# 198options CPU_ATHLON_SSE_HACK 199options CPU_BLUELIGHTNING_3X 200options CPU_BLUELIGHTNING_FPU_OP_CACHE 201options CPU_BTB_EN 202options CPU_DIRECT_MAPPED_CACHE 203options CPU_DISABLE_5X86_LSSER 204options CPU_DISABLE_CMPXCHG 205#options CPU_DISABLE_SSE 206options CPU_ELAN 207options CPU_ELAN_PPS 208options CPU_ELAN_XTAL=32768000 209options CPU_ENABLE_LONGRUN 210options CPU_FASTER_5X86_FPU 211options CPU_GEODE 212options CPU_I486_ON_386 213options CPU_IORT 214options CPU_L2_LATENCY=5 215options CPU_LOOP_EN 216options CPU_PPRO2CELERON 217options CPU_RSTK_EN 218options CPU_SOEKRIS 219options CPU_SUSP_HLT 220options CPU_UPGRADE_HW_CACHE 221options CPU_WT_ALLOC 222options CYRIX_CACHE_WORKS 223options CYRIX_CACHE_REALLY_WORKS 224#options NO_F00F_HACK 225 226# Debug options 227options NPX_DEBUG # enable npx debugging 228 229# 230# PERFMON causes the driver for Pentium/Pentium Pro performance counters 231# to be compiled.

The drawback is a moderate (up to 1/HZ seconds) 262# potential increase in response times. 263# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 264# to achieve smoother behaviour. 265# Additionally, you can enable/disable polling at runtime with help of 266# the ifconfig(8) utility, and select the CPU fraction reserved to 267# userland with the sysctl variable kern.polling.user_frac 268# (default 50, range 0..100). 269# 270# Not all device drivers support this mode of operation at the time of 271# this writing.
